A local multiple proper generalized decomposition based on the partition of unity
(John Wiley & sons, 2019-10-12)
Article
Accés obertIt is well known that model order reduction techniques that project the solution of the problem at hand onto alow-dimensional subspace present difficulties when this solution lies on a non-linear manifold. To overcomethese ... -
A non-intrusive proper generalized decomposition scheme with application in biomechanics
(John Wiley & Sons, 2017-09-07)
Article
Accés obertProper generalized decomposition (PGD) is often used for multiquery and fast-response simulations. It is a powerful tool alleviating the curse of dimensionality affecting multiparametric partial differential equations. ... -
A numerical study on hydraulic fracturing problems via the proper generalized decomposition method
(2020-02-01)
Article
Accés obertThe hydraulic fracturing is a nonlinear, fluid-solid coupling and transient problem, in most cases it is always time-consuming to simulate this process numerically. In recent years, although many numerical methods were ... -
A practical proposal for the use of origin destination matrices in the analysis, modeling and simulation framework for traffic management
(2013)
Text en actes de congrés
Accés obertDealing with traffic demand trip matrices to feed models to support decisions in traffic management is still a problem that deserves research efforts, aimed to find practical solutions applicable in the short term horizon, ... -
A Proper Generalized Decomposition (PGD) approach to crack propagation in brittle materials: with application to random field material properties
(Springer, 2020-02)
Article
Accés obertUnderstanding the failure of brittle heterogeneous materials is essential in many applications. Heterogeneities in materialproperties are frequently modeled through random fields, which typically induces the need to solve ... -
A set simulation approach to the computation of invariant sets for nonlinear systems
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Comunicació de congrés
Accés restringit per política de l'editorialGiven a nonlinear discrete-time system, previous works exist that compute invariant sets as finite unions of boxes. Set inversion algorithms based on interval arithmetic are used to obtain inner approximations of the one ... -
